1, Printing accuracy and detail performance
When measuring the quality of a printing system, printing accuracy is undoubtedly the primary consideration. High precision means being able to print finer and more realistic models, meeting users' pursuit of details. Among numerous printing systems, Lens (stereolithography) and SLM (selective laser melting) printing systems stand out for their excellent printing accuracy.
The Lens printing system uses a laser beam to accurately scan the surface of liquid resin, solidify it into thin layers, and stack them layer by layer to construct a three-dimensional model. Due to the precise control of the laser beam, the Lens printing system can achieve micrometer level printing accuracy, and the printed model surface is smooth, delicate, and rich in details.
The SLM printing system uses laser melting of metal powder for layer by layer stacking to construct metal parts. Although its printing accuracy may be slightly lower than Lens, the metal parts printed by SLM have a dense internal structure and excellent mechanical properties, which can meet the high requirements for strength and durability in application scenarios.
2, Material diversity and applicability
The material selection of the printing system directly affects the printing effect and application field. An excellent printing system should be able to support printing of multiple materials to meet the needs of different users.
The Lens printing system mainly uses photosensitive resin materials, which have good fluidity and curing properties, and can print complex and fine structures. At the same time, photosensitive resin materials also have good environmental performance, meeting the requirements of modern manufacturing for environmental protection.
The SLM printing system mainly uses metal powder materials such as titanium alloy, aluminum alloy, stainless steel, etc. These materials have excellent mechanical properties and corrosion resistance, and can print metal parts with complex structures and excellent performance. In addition, the SLM printing system also supports mixed printing of multiple metal materials, providing designers with more creative space.
In addition to Lens and SLM printing systems, FDM (fused deposition modeling) printing systems are also favored by users for their wide range of material choices. The FDM printing system can use various thermoplastic materials such as ABS, PLA, etc. to print models with different properties and appearances.
3, Printing speed and efficiency
While pursuing high quality, printing speed and efficiency are also key concerns for users. An efficient printing system can shorten the production cycle and improve production efficiency.
The Lens printing system, with its fast curing feature, can complete the printing of models in a relatively short period of time. However, due to its layer by layer solidification working mode, the printing speed of Lens printing system may be affected by model complexity and layer height.
The printing speed of SLM printing system is relatively slow because the melting and solidification process of metal powder requires a long time. However, SLM printing systems can print multiple parts at once without the need for subsequent processing, thereby improving overall production efficiency.
FDM printing systems are favored by users for their fast printing speed and wide range of applications. The FDM printing system uses a heated extrusion head to extrude thermoplastic materials and stack them layer by layer to form a three-dimensional model. This printing method is not only fast, but also capable of printing models with complex structures.
4, Software compatibility and usability
An excellent printing system should have good software compatibility and ease of use, so that users can easily perform model design, slicing, and printing operations.
Lens and SLM printing systems are usually equipped with professional printing software and slicing software, supporting multiple file formats for import and export, such as STL, OBJ, etc. These software typically have user-friendly interfaces and powerful features that can help users quickly complete model design, slicing, and print parameter settings.
FDM printing systems typically use open-source printing and slicing software such as Cura, PrusaSlicer, etc. These software not only have powerful functions, but also have good compatibility and scalability, which can meet users' pursuit of printing quality and efficiency.
